- Undercarriage Wear
- Given the compact design of the CAT 302.5, its undercarriage takes on a lot of stress, especially when working on uneven terrain. Tracks and rollers can wear out over time, leading to less efficient movement and the potential for costly repairs. Operators should regularly inspect the undercarriage and replace any worn-out parts before they affect the machine's performance.
